Turing GPUs also ship with an enhanced NVENC encoder unit that adds support for H.265 (HEVC) 8K encode at 30 fps. The new NVENC encoder provides up to 25% bitrate savings for HEVC and up to 15% bitrate savings for H.264. Turing’s new NVDEC decoder has been updated to support decoding of HEVC 4:4:4 8/10/12-bit video streams, and it also supports VP9 10/12-bit HDR similar to Pascal GP102/107/108 and Volta GV100 GPUs. Turing improves encoding quality compared to prior generation Pascal GPUs and compared to software encoders. Figure 13 shows that on common Twitch and YouTube streaming settings, Turing’s video encoder exceeds the quality of the software-based x264 encoder using the fast settings, with dramatically lower CPU utilization. 4K streaming is too heavy a workload for encoding on typical CPU setups, but Turing’s encoder makes 4K streaming possible.
